(Bloomberg) -- One of the companies that launched a futures-based Bitcoin ETF is looking to debut another -- with amped-up returns. 

Valkyrie, which was second to market with a futures-based Bitcoin fund, on Tuesday filed an application with the U.S. Securities and Exchange Commission to launch the Valkyrie XBTO Levered BTC Futures ETF, which would trade under the ticker BTFX. The fund would juice returns by delivering 1.25 times the return of a Bitcoin reference price, according to a filing. It would list on Nasdaq and would be able to hold derivatives such as futures and options.  

Two ETFs tracking Bitcoin futures premiered last week, both with much fanfare. The first -- the ProShares Bitcoin Strategy ETF, or ticker BITO -- accumulated more than $1 billion in assets in just days.
